- Migrate 5 OWL components from deprecated useService("rpc") to useService("orm") for Odoo 19
- Fix _paginate() signature mismatch across 6 controllers (dual calling convention)
- Fix taxonomy API serializers referencing non-existent fields (icon, difficulty)
- Fix branding controller validate_token() called with wrong arguments
- Add .sudo() to exam template/question model access under auth='none'
- Restore missing encoach_core files (security groups, permissions seed, core models)
- Create encoach_api shared controller utilities module
- Add Entity list/form/search views and menu items
- Add Taxonomy (Subjects/Domains/Topics) views and menu items
- Fix deprecated XML group expand="0" patterns across 15 view files
- Remove stale model references from adaptive __init__.py and access CSV
- Update .gitignore to exclude local dev artifacts

Tested: 97% pass rate (64/66 tests) across UI navigation, CRUD, and API endpoints.
